KNOB-SPINDLE.

SPECIFICATION forming part of Letters Patent No. 734,117, dated July 21,1903.

Application filed April 25, 1903- To all whom it may concern.- I

Be it known that 1, CHARLES J. OALEY, a

citizen of the United States, residing at New Britain, Hartford county,Connecticut, have invented certain new and useful Improvements inKnob-Spindles, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in door locks and latches, andparticularly to what is known as the knob-spindle.

It is the main purpose of my invention to provide an improvement in thespindle portion of a door lock or latch, so that the same will have inaddition to a swivel movement I 5 a compensating movement. Bythisimprovement if it happens that a door-lock is not fitted to a doorso that the case will stand exactly parallel with the surface of thedoor the knob-spindle may, nevertheless, be propzo erly fitted to theoutside of the door and enter the lock-case in a slightly-oblique lineand operate in the hub without binding or cram ping.

In the accompanying drawings, Figure 1 is a vertical section of aportion of a door and 2 5 of parts of a lock or latch fitted with aspindle constructed to embody my invention. Fig. 2 is an elevation,partly in section, of the spindle detached.

1 is a portion of a door.

2 is a lock-case.

3 31 are hub-sections capable of being independently revolved or turnedto operate those parts of a lock or latch which are usually connectedtherewith. These hubsec- 35 tions may be revolved independently by meansof knobs 4 41.

5 51 are two sections of a spindle which I terma compensatingswivel-spindle. The inner ends of these spindle-sections 5 51 are 40connected by meansof a coupling 6. This coupling is best seen in Fig. 2,in which it will be observed that it serves as a doubleheadedlink,'having somewhat the appear ance of a miniature dumb-bell, in thatthe ends are spherical and are united by a narrow construction. Thiscoupling 6 permits of a universal movement of the spindle-sections 551,-that is, they may be rotated independently of each other and theymay also Serial No. 154,240. (No model.)

tilt or swing out of line. In practice one or both of the hub-sectionsmay have a cavity to receive the spindle, and said cavity ispreferablyslightly larger than the spindle, so as to allow of thecompensating movement. Obviously this oscillatory movement of one orboth of the spindle-sections may be permitted by other arrangementswithout departing from the spirit or scope of the invention. In thedrawings, Fig. l, I have shown the spindle-passage of the section 51slightly larger than the spindle end located therein. Of course theother section might be similarly enlarged, if desirable.

What I claim is- 1. An improvement in door locks andlatches comprising,a spindle consisting of a plurality of sections arranged end to end anda coupling connecting said ends to permit one of said spindle-sectionsto oscillate relatively to the other. 2. An improvement in door locksand latches comprising, a spindle consisting of a plurality of sectionsarranged end to end, and a coupling connecting said ends and arranged topermit one of the said spindle-sections to swivel and oscillaterelatively to the other.

3. An improvement in looks and latches comprising, a spindle consistingof a plurality of sections arranged end to end, and av universalcoupling loosely connecting said ends to permit each spindle-section toswivel or oscillate relatively to the other.

4. Animpr'ovement in looks and latches comprising a spindle consistingof a plurality of sections arranged end to end and a universal couplingconnecting said ends to permit one of the said sections to oscillaterelatively to the other, said universal coupling including two headsunited by a connection of smaller diameter, said heads being held inbearings in the adjacent ends of said spindle sections.
